Depth of field:
Depth of field is the range of distance within the subject that is acceptably sharp. The depth of field varies depending on camera type, aperture and focusing distance, although print size and viewing distance can influence our perception of it.

Self timer:
This is a device on a camera that allows you to make a delay between pressing the shutter release and the shutter firing. It is most commonly used to allow the photo taker to take a picture of themselves. An example of this is when you take a family picture and you want everyone to be in the picture, you put the camera on self timer and then after pressing the shutter release you can get in the picture before the photo is taken.

ISO (international standardization organization):
Determines how sensitive to image sensor is to light. The lower the ISO the slower the speed, and the higher the ISO number the faster the speed. For low ISO you will have a better quality picture, and a higher ISO you have a more grainy photo.

Auto Focus vs Manual Focus:

Auto Focus is the setting on the camera that allows to choose the distance and the picture, and the camera will focus the lends for you. You would choose this setting when you are taking a picture of a person from a distance. Manual focus is adjusting the focus of the lends by your own hand. You would choose manual focus when the object of the image is complex. You would take this picture when you want a close up such as a flower.
